I've had the good fortune to travel extensively on nature tours around the world. Fabiano is world class in his knowledge, enthusiasm, smoothness handling logistics, flexibility with changing circumstances, and patience with a disparate group. When our son suddenly needed a bathroom, he (1) found one in moments down the next dirt road, (2) declared this an excellent spot for the group to search out a certain rare bird, and (3) enthusiastically led everyone in a very successful hike. Was this a complete change in itinerary? Sure. But handled with such aplomb that no one even noticed. 

He kept mental track of every species observed on our 2-week trip, and every time we saw a new one he was as excited as could be. He's a fantastic birder, recognizing every call and silouhette we came across (several hundred!) - and able to successfully imitate most. Ask him for his giant river otter call!
